Description

Convertible shoes {size changable shoes}

The present invention relates to a shoe, and more particularly to a functional variable shoe that can be adjusted in size.

A shoe is a general term for articles made to be worn on a foot in order to protect the foot, to harmonize with clothing, and to improve walking or work efficiency, and is generally made of various materials such as rubber, cloth, plastic, or leather. These shoes have a variety of shapes according to the environment or purpose, but in common when the user wears the sole to the front of the sole, and the outer skin that is coupled to the above-mentioned sole so as to surround the foot so that the shoes are fixed have.

These shoes have been used by humans for a long time, and have been developed in terms of materials and functions according to the development of culture and science, but their size is determined by the insole and its outer skin. However, there is a disadvantage that a new purchase is required as the foot grows or when shoes of different sizes are required according to the purpose.

In other words, as the size of the shoes remains unchanged, children of growing age should purchase shoes of appropriate size from time to time according to the rapid growth rate of the feet.In addition, even if they are adults, they wear shoes that are worn with bare feet or thin socks in the summer. You can't wear it while wearing thick socks, and you have to buy shoes of different sizes. In particular, in recent years, a very solid material is used according to the development of various materials, and it keeps its appearance in good condition. Despite their size, they have no choice but to buy new shoes, which makes them more economically inefficient.

In order to solve this problem, Patent No. 1998-021230 introduces a variable size adjustable shoes, the side of Figure 1 and the exploded side view of Figure 2 and the front and rear soles included therein The structure will be described in more detail with reference to FIGS. 3A and 3B, respectively.

An outer shell 1 having a variable portion 2, which forms an outer shape of a shoe, and an insertion groove 3a having a first locking groove 3aa formed on an inner surface thereof, which is bonded to the lower portion of the outer shell 1, respectively. It consists of a front sole 3 having a, and a rear sole 4 having a locking end (4a) to be separated or coupled with the front sole 3, wherein the variable portion (2) is a nonwoven fabric ( It consists of 2a) and the cover part 2b, and has the structure which the cover part 2b covers the outer surface of the nonwoven fabric 2a.

In addition, the rear part of the front sole 3 and the rear part of the rear sole 4 have a second locking groove 3ab and a protruding end 4b, respectively, so that they are folded into the second locking groove 3ab. As the protruding end 4b is made to flow, the length of the front sole 3 and the rear sole 4 may be changed in an assembled state. In the assembling process of the shoe, first, the protruding end 4a of the rear sole 4 is inserted into the insertion groove 3a of the front sole 3, so that the protruding end 4a is inserted into the insertion groove 3a. Through the first locking groove 3aa, and successively passing through several first locking grooves 3aa, the locking end of the second locking groove 3ab of the front sole 3 and the rear sole 4; Let (4b) be combined.

Then, the upper surface of the combined front sole 3 and the rear sole 4 is configured by accurately positioning and bonding the outer skin 1, while the user wants to reduce the size of the shoe, the front sole ( 3) by holding the rear sole 4 forward, the protruding end 4a of the rear sole 4 is different from the first locking groove 3aa of the front sole 3 by the first locking groove 3aa. To make the shoe smaller.

However, the general variable shoes having such a configuration has some fatal drawbacks in use, because first of all, the variable part 2 consisting of the nonwoven fabric 2a and the cover part 2b is relatively thicker than other outer skins. It gives a dull appearance in appearance, and when the shoe is reduced, the nonwoven fabric 2a or the cover portion 2b is wrinkled or crumpled (crumple), has the disadvantage of being unsightly. In addition, the variable part 2 is made of a non-woven fabric, such as a material that is relatively weaker than other parts, and often breaks when there is a severe movement or movement in the state of wearing shoes, in particular, the bottom of the variable part 2 Since the bottom and the upper surface of the rear outsole (4) is not coupled, when the shoes are folded, this part protrudes and at the same time there is no waterproof function has a disadvantage that can not be used in rain or snowy days or water.

In the coupling of the front sole 3 and the rear sole 4, as the fixing means thereof, only the first locking groove 3aa and the locking end 4a of the insertion groove 3a are used. When it is difficult to apply excessive force, there is a problem that the front sole 3 and the rear sole 4 are easily detached.

This, in particular, considering that the above-described variable shoes are made for those who have a large amount of activity, such as children in the growing season, the detachable structure of such shoes and the vulnerable structure of the variable portion will bring a lot of restrictions in use.

The present invention has been made to solve the above problems, and has a strong support for maintaining a constant appearance irrespective of the movement of the operator, at the same time easy to adjust the size of the improved variable shoes with the function of waterproof The purpose is to provide.
